Definitions
- the present invention relates to a frame part for a tubular heat exchanger.
- Tube heat exchangers consist of a number of tubes running parallel to each other, through which a heat exchange medium flows.
- the parallel tubes form a tube body.
- Such side parts with expansion beads are only suitable for the expansion compensation in the longitudinal direction. Nevertheless, the presence of at least one expansion bead as a weakening of the longitudinal stiffness of the frame part is not sufficient to achieve a complete decoupling of the tube body and the frame part. In addition, the production of side parts with expansion beads is associated with a high level of production effort and great demands on the forming tools.
- a frame part for a tube heat exchanger has a number of tubes running parallel to one another, which form a tube body and through which a heat exchange medium flows.
- the tube body is surrounded by frame parts on at least two sides running parallel to the tubes.
- Such a deflection in the shape of the frame part has the effect that not only is there a reduced longitudinal rigidity, but also flexibility in the direction transverse to the course of the frame part.
- This enables not only thermal expansion of the tube body along the direction of the course of the tubes, but also in a transverse direction thereto. to catch.
- the introduction of temperature-induced stresses on the tubes due to different thermal expansion between the tube body and frame parts is avoided.
- the roots of the tubes on other components which may have been produced by welding or soldering, are relieved of stress, an increased quality and reduced leakage of the tubes in these areas are advantageously achieved.
- thermal expansion element provides that it consists of the material of the frame part itself.
- the frame part including the thermal expansion element consists of components with the same physical behavior and, if, according to an advantageous embodiment, it is integrally connected to the frame part on at least one side, can be produced from one piece of material.
- Particularly preferred embodiments of the invention provide that the frame part and the thermal expansion element are connected to one another on both sides of the thermal expansion elements, so that the entire unit can be produced from a single piece of material.
- the thermal expansion element is essentially ⁇ -shaped, the thermal expansion element protruding, in particular away from the tubes, out of the plane of the frame part.
- a height offset can be formed in the area of the thermal expansion element in the plane of extension of the frame part on both sides of the thermal expansion element. Such a height offset has the advantage that the frame part has different heights, for example between a collecting body in which the. Can open tubes and balance the tubes themselves and at the same time has a high flexibility and low rigidity both in this vertical direction and in the longitudinal direction of the frame part.
- Another advantageous embodiment of the invention provides that two ⁇ -shaped sections are formed one behind the other, the curvature sections of which preferably lie on the opposite sides of the frame part.
- the thermal expansion element can, in particular, Include a height offset in the plane of extension of the frame part on both sides of the thermal expansion element.
- Such a double ⁇ -shaped design makes it possible to integrate a large length of material into the thermal expansion element and thus, particularly in the longitudinal direction of the frame part, to integrate a high thermal expansion capacity.
- a further embodiment of the invention provides that the thermal expansion coefficient of the frame part in the area of the thermal expansion element is at most the same, preferably less than the thermal expansion coefficient of the tubes. This measure ensures that the stretchability of the frame part in the direction of extension of the tubes is at most the same, preferably less, and thus a load due to different thermal expansion between the frame part and the tubes is largely avoided. With such a configuration, an adaptation to the thermal behavior of the tubes in the event of temperature fluctuations is achieved not only by the low mechanical rigidity of the frame part, but also by the correspondingly high thermal expansion in the region of the expansion element.
- the thermal expansion element is designed as at least one web, which does not extend across the entire width of the frame part.
- the thermal expansion element preferably consists of two such webs, which run on both sides at the edge of the frame part. This measure on the one hand results in a lower mechanical rigidity and thus a better extensibility of the frame part in the area of the thermal expansion element in the longitudinal direction of the frame part, and on the other hand saves material in an advantageous manner, which leads to a lower weight of the frame part, which is a desired advantageous measure represents. Due to the marginality of two webs, a closed, straight outer contour of the frame part is maintained at the same time.
- a thermal expansion element is formed in at least one section of the frame part corresponding to an end region of the tubes. This is preferably the area of a loading Fastening, in particular welding or soldering, the pipes on another body, such as a manifold or a distributor pipe.
- the tube body of a heat exchanger extends in particular between a distributor pipe and a header pipe, the inflowing heat exchange medium first being led into the distributor pipe and the mass flow being distributed through the distributor pipe to the different tubes of the pipe body, thereby increasing the surface area of the heat-conducting elements, which promotes heat exchange becomes.
- the partial flows are collected again in the collecting pipe and the total flow is brought together.
- the tubes of the tube body are fastened on both sides by welding or soldering into corresponding perforations on the distributor tube and header tube.
- these fastening points represent particular weak points with regard to the mechanical rigidity of the tubular heat exchanger.
- the thermal expansion element is formed in particular in this end region of the tubes, a high flexibility of the frame part is generated here.
- the frame part extends in particular between the header pipe and the distributor pipe over the entire length of the pipes and in particular has a thermal expansion element on both sides in the end region of the pipes.
- a further advantageous embodiment of the invention provides that the outer ribs surrounding the tubes are thermally contacted with these tubes.
- These outer ribs are in particular oriented transversely to the longitudinal direction of the tubes and are in particular terminally at least on the one hand against a frame part and are preferably connected to this.
- the thermally contacted outer ribs increase the heat exchange surface, whereby the heat transfer between the outer ribs takes place through heat conduction in the material.
- the attachment can advantageously be done by brazing. A closed body is thus created by the frame parts.
- this is reduced between the thermal expansion elements to a meandering material web, which preferably has laterally protruding, flat, material tongues aligned in the plane of the frame part. It is in particular possible for the outer ribs surrounding the tubes to be connected to the frame part in the region of the material tongues, in particular by welding or soldering.
- Figure 1 shows a first embodiment of a frame part according to the invention
- Figure 2 is a side view and top view of a second embodiment of a frame part according to the invention, a height offset being integrated in the frame part in the region of the expansion element;
- FIG 3 shows a heat exchanger with a frame part according to Figure 2;
- Figure 4 shows a further embodiment of a frame element according to the invention.
- Figure 5 shows a heat exchanger with a frame part according to Figure 4.
- FIG. 1 shows the frame part 10, which is divided into two outer sections 12 and a middle piece 13 by the two thermal expansion elements 11 integrated into the frame part.
- the thermal expansion element 13 is formed from a web 14 which describes an essentially ⁇ -shaped curve and extends to the edge, that is to say the outer contour of the frame part 10.
- the width of the web 14 is less than the width of the frame part 10, so that a web 14 is arranged on both sides of the edge and a middle cut 15 is located between them, which is free of material.
- FIG. 2 shows a longitudinal section and a top view of another frame part 10 in a sectional view.
- thermal expansion element 11 which is formed from two webs 14, between a central piece 13 and an outer section 12, the webs 14 running at the edge in relation to the outer section 12, while the central piece 13 has a greater width than the outer section 12 having.
- central section 15 between the two webs 14 which is free of material. This saves material and weight and reduces mechanical rigidity.
- the design of the frame part in FIG. 2 essentially corresponds to the design of the frame part in FIG. 1.
- the thermal expansion element 11 there is a height offset h between the outer section 12 and the center piece 13.
- FIG. 3 shows the mounting position of a frame part 10 according to FIG. 2 on a heat exchanger 30.
- the heat exchanger 30 is laterally limited by the distributor pipe 31 into which the heat exchange medium flows and a header pipe 32 from which the heat exchange medium flows again between the distributor pipe 31 and the collecting pipe 32 are parallel tubes, which are not shown in detail, as well as outer ribs running transversely to the tubes and forming the tube body 33.
- the center piece 13 of the frame part 10 extends along the course of the tube body and parallel to the course of the tubes in the tube body, while a heat expansion element 11 is formed in each case in the transition between the collecting tube 32 and the tube body 33 or the distributor tube 31 and the tube body 33, for example from the FIG. 2 can be seen and connects the middle piece 13 of the frame part 10 to an outer section 12, which is located on the outside and which is fastened to the collecting pipe 32 or distribution pipe 31.
- the distributor pipe 31 and the collecting pipe 32 expand especially in the vertical direction, while the tubes of the tubular body 33, especially in the E 'rstreckungscardi of the frame member 10, ie in the longitudinal direction, to change.
- the variability in the height offset h compensates for the different expansion in the vertical direction, while the ⁇ - Shape of the thermal expansion element 11 takes place in the longitudinal direction in the course of the tubes.
- the thermal expansion elements 11 of the frame part 10 are located in particular in the section in which the transition between the distributor pipe 31 or the collector pipe 32 and the tubes of the tube body 33 is given, which is a particular structural weak point.
- Figures 4 and 5 show a further embodiment of a frame part according to the invention, here again the frame part 10 has two outer sections 12 and a center piece 13, which are connected to each other via a thermal expansion element 10, which is a multiple of the material thickness of the material of the frame part 10 deviates from the plane of the frame part 10, which is defined in particular by the plane of the center piece 13.
- the center piece 13 of the frame part 10 is reduced to a meandering material web 16, from which material tongues 17 project in sections, which bear against the tube body 33 of the heat exchanger 30 and are attached to it.
